PAMP-tracheo: Vascular plants in the research project on dark diversity of plant communities in the centre-east of Navarra (Spain)

Study Extent

The specimens were collected in an area of 314 km2, defined by a circle of 10 km radius, centred in the municipality of Romanzado (centre-east Navarra, Spain). Samples were collected between the years 2019 and 2021, on a yearly basis.

Sampling

All vascular plants present in each plot were identified. Plant specimens were collected for appropriate identification and voucher.

Method steps

1. Plant collection. Plant vouchers were selected and collected in the field.
2. Identification to species or subspecies level. Identification was performed between 2019 and 2021 by R. Ibáñez according to Flora iberica (Castroviejo 1986-2021).
3. Plant conservation. Specimens were dried and pressed for conservation using standard protocols. Vouchers were deposited in the herbarium of the University of Navarra (PAMP).
4. Numbering and digitization of vouchers. From 2019 to date, each specimen was labelled, with a unique collection number, and digitized, using Elysia software (v2.0 Pando et al.).
5. Species identification. Identification of herbarium specimens was done using Flora iberica (Castroviejo 1986-2021).
6. Names of municipalities, localities and place names were standardized according to Toponimia Oficial de Navarra (http://toponimianavarra.tracasa.es/).
7. Georeferencing. Localities were georeferenced using geographic coordinates. Datum and uncertainty were also assigned.
8. Internet exportation. Data were exported from the Elysia database under a Darwin Core format (Wieczorek et al. 2012).
9. Data checking and validation. Coordinates, characters and format of dates were checked for possible mistakes using Darwin test software (v3.4 Pando et al.). This software allowed validating data in the Darwin Core format.
10. Metadata were documented and the dataset was published in the GBIF data portal using the Integrated Publishing Toolkit (IPT v2.5.2) of GBIF.es (http://ipt.gbif.es/).

Out of a total of 1517 specimens, all were identified to species or subspecies level. They belong to 491 species or subspecies and 72 families of vascular plants.
